Use of a Bipolar Device (LigaSure) to Seal the Appendiceal Stump in Pediatric Laparoscopic Appendectomy: 10-year Latin-American Experience.

Article Synopsis
- This study evaluates the safety of using electrosurgical devices for closing the appendiceal stump during laparoscopic appendectomy in pediatric patients, as there was limited knowledge on this technique.
- Conducted from 2012 to 2021 with 209 patients under 18 years old, the study found no cases of stump leakage and only a minimal rate of unrelated surgical site infections, suggesting favorable outcomes.
- The findings indicate that using a bipolar sealing device for appendiceal stump closure is feasible in children and warrants further research to confirm its efficacy and safety.
Magnetoelectric coupling is achieved near room temperature in a spin crossover Fe molecule-based compound, [Fe(1bpp) ](BF ) . Large atomic displacements resulting from Jahn-Teller distortions induce a change in the molecule dipole moment when switching between high-spin and low-spin states leading to a step-wise change in the electric polarization and dielectric constant. For temperatures in the region of bistability, the changes in magnetic and electrical properties are induced with a remarkably low magnetic field of 3 T.

Storage conditions represent a key source of variability that may contribute to biomass quality variations from the time of harvest until delivery to the biorefinery. In some cases, substantial microbial degradation can take place during storage.
